Many stock rebound valving systems are grossly inadequate. No matter what modifications are attempted, the stock valves will never perform with precision or control. If you race or simply want the best, Race Tech's Rebound Gold Valves are the solution to improved traction. Used by major factory teams. These valve increase flow area, putting valving control on the shim stack instead of the piston. This results in outstanding tuneability, improved control and traction.
